Frequently asked questions

What is Calk AI ?
Calk AI is a SaaS platform that lets you build AI-powered assistants connected to all your business tools and knowledge—in minutes, not months.
Who is Calk AI for ?
Calk AI is used by fast-moving teams, startups, and enterprises that want custom AI assistants deeply connected to their day-to-day tools and workflows.
What makes Calk AI different ?
Most ‘AI chatbots’ are standalone. Calk AI connects to your real business data, lets you blend multiple top AI models, and automates actual, useful tasks. Not just chat. Not just hype.
What makes multi model useful in Calk AI ?
At the moment, the only way to add additional information to invoices is to add the information to the workspace's name.
Why connecting my internal knowledge ?
Because the more Calk AI knows about your unique business, the smarter—and more reliable—your agent gets. Centralize knowledge, reduce context-switching, and get answers that just work.
Is my data safe with Calk AI?
Yes. We use industry-standard encryption, never use your data to train public models, and let you control what’s connected, stored, and deleted—your data, your rules.
Do I need technical skills or coding to use Calk AI?
Plans are per workspace, not per account. You can upgrade one workspace, and still have any number of free workspaces.
How does billing work?
Plans are per seat, so per account. You can upgrade one pers, and still have any number of free workspaces.
